Labrum wide, transverse. Mentum and labium narrow, with distinctly elongate apical labial palpomere (Fig. 12). Preapical segment of maxillary palpus moderately long, 1.5 times as long as wide, and as wide as apical segment; apical segment about twice as long as preceding segment, from middle gradually narrowing toward apex (Figs 5, 11, 18). Gular sutures with shortest distance located at level of posterior third of eyes (Fig. 12). Antenna moderately short, exceeding apical third of elytra, with elongate antennomeres 5 - 10 and long preapical setae, antennomeres 3 - 11 covered by dense pubescence; basal antennomere moderately wide, 1.5 times as long as 2, antennomere 2 ovoid, about twice as long as wide and slightly shorter than 3, 3 and 4 as wide as 2, 5 - 7 slightly shorter than 4, 8 and 9 slightly shorter than 7, 10 distinctly shorter than 9, apical antennomere 1.6 times as long as 10, from middle gradually narrowed toward apex (Fig. 3).

Laterobasal and basal portions of pronotum with dense and fine punctation (Fig. 3). Pronotal hypomeron and postcoxal process well developed; intercoxal process elongate and moderately wide; prosternum with distinct median carina (Figs 11, 18). Scutellum large and wide, with rounded apex. Metaventrite wide, convex. Elytra convex, slightly longer than wide, about twice as long as pronotum, indistinctly widened in middle, reaching basal margin of abdominal tergite VI, with widely rounded apical margins (Fig. 17); shoulders of elytra rounded; lateral portions narrow, explanate; surface of elytra without visible elevations. Punctation sparse and moderately small, each elytron with longitudinal rows of vague serial punctures in middle (Fig. 3). Hind wings fully developed. Legs long (Fig. 7); procoxae wide, protruding ventrad, contiguous; mesocoxae large, convex; metacoxae strongly transverse; pro-, meso-, and metatrochanter relatively narrow, elongate (Figs 11, 12); all femora widest at about middle, profemora slightly wider than meso- and metafemora; pro- and mesotibiae about as long as femora; protibiae covered with dense long setae; protarsomeres 1 - 5 as in Fig. 8; mesotibiae indistinctly curved in middle, inner side of each mesotibia with large and wide subtriangular, fin-shaped tooth in middle (Fig. 7, arrows); meso- and metatibiae covered by very dense, long and strong setae (including apex of tooth on each mesotibia); metatibiae with additional very long setae; metatibiae distinctly longer than metafemora, slightly widened in about middle, covered by dense, strong and long setae, with a few additional spines around apical margin; all tarsi 5 - segmented, all tarsi combined shorter than tibia; tarsomeres 1 - 4 with long and dense lateral setation; apical tarsomere about as long as preceding three tarsomeres together; tarsal claws simple, without modifications (Fig. 7).
